why do our ears hurt in airplanes

If you have ever flown with your parents, you will remember them encouraging you to chew gum or drink a juice box when the plane was taking off and landing. The reason they did this was to lessen or prevent the earache you can get when flying. Actually, you can get an earache anytime you travel up or down in a short period of time. ItБs just that plane trips cause the biggest swings away from, or back to, Mother Earth. The question is, why do you feel this sort of pain and how does swallowing make it better? To answer this question, we need to review the anatomy of your ear. The eardrum is positioned between two air-filled spaces: the ear canal and the middle ear. The eardrum is made from a special type of skin that resembles an audio speaker. And just like a speaker vibrates to reproduce

 why is the social contract theory important

why is the social contract theory important

Government exists because it is generally preferable to the alternative, which is the absence of government. The benefits of organizing society under centralized authority almost always outweigh the costs. According to the philosopher, the life of humans in the state of nature is "nasty, brutish, and short. " Because no higher authority exists to impose order, humans, equally vulnerable in nature, are in constant danger of violence from each other. They therefore agree to surrender their precarious natural freedom to governments (in Hobbes theory a Leviathan, or monarch) for security. Government exists to insulate us from the arbitrary violence of nature and protect us from each other. An 18th century philosopher, offers an alternative explanation. According to Rousseau, mankind in the

why do non christians celebrate christmas and easter

Jerry. , on 21 March 2015 - 06:39 PM, said: Yes - this. It s purely cultural for us. We have the four days off, the kids love the chocolate egg hunts and the idea of the Easter bunny. We generally do a big family lunch on one of the days - if I m hosting on Good Friday I make a point of doing a slow roast lamb - it s quite funny to see the guests who have initially stated a no meat on Good Friday line cave in (I obviously do serve vegetarian dishes for the hard liners. ) Same as Christmas - my anthem for that time of year is Tim Minchin s White Wine in the Sun - yes I have all the usual objections, but I just really like it. ...

WEDNESDAY, FEBRUARY 21 -- 7 PM Go Tell It on the Mountain, originally published in 1953, is Baldwin's first major work, a novel that has established itself as an American classic. With lyrical precision, psychological directness, resonating symbolic power, and a rage that is at once unrelenting and compassionate, Baldwin chronicles a fourteen-year-old boy's discovery one Saturday in March of 1935 of the terms of his identity as the stepson of the minister of a Pentecostal storefront church in Harlem. Baldwin's rendering of his protagonist's spiritual, sexual, and moral struggle toward self-invention opened new possibilities in the American language and in the way Americans understand themselves. One of the fall books that I m really looking forward to is Benjamin Moser s biography of

 why do we get hiccups when we laugh

why do we get hiccups when we laugh

Dr. Michael Roizen, right, and Dr. Mehmet Oz. Question: I hiccup when I laugh really hard. What is the reason for that? Answer: Welcome to the club. Many people experience singultus (that's science-speak for hiccups) when they laugh, cry or experience some strong emotion. But why it happens is one of those medical mysteries, like why public speaking and seeing the love of your life both can cause the sensation that butterflies are rioting in your stomach. It has to do with nerves that are related to your vagus (which conveys sensory information about the state of the body's organs to the central nervous system). But unlike the city, what happens in vagus doesn't stay in vagus, so you hiccup as well as laugh. Good news: They're nothing to worry about unless you can't make your hiccups go

 why do we need to save endangered animals

why do we need to save endangered animals

Is it Important to Save Animals from Extinction? Some people may ask why bother with conservation? We now realise that it is important to maintain the planet s biodiversity, that it is the richness (variety) of animal and plant life, its abundance and wild habitats that keeps us all healthy and happy. The more species disappear, the more entire eco-systems become vulnerable and would eventually fall apart as the links in the food chains become broken. For example certain animals only eat certain plants and those plants may need that animal to pollinate it or spread its seed. Without one, the other is also likely to die out. From a selfish point of view, we humans never know how valuable a species of animal or plant may be for us in the future, perhaps as food, medicines (particularly
